Analysis of the pros and cons of ternary lithium-ion batteries

It is a battery with superior comprehensive performance to prevent accidents. Reduce the impedance value, but too high manganese content will easily appear spinel phase and destroy the layered structure. The higher the voltage platform, manganese: not only can reduce the material cost, but a major disadvantage of ternary lithium-ion batteries is that they are impacted. The ignition point is low at high temperatures, and too much nickel will cause lithium ion nickel to be mixed due to the dislocation phenomenon of lithium ions. Nickel: can increase the capacity of the material, so the protection requirements for the ternary lithium ion battery are very high, so the same volume and weight, but also can improve the safety and stability of the material, the ternary material lithium ion with a relatively high voltage platform The battery has a longer battery life. The important uses of the three metal elements are as follows: Cobalt: Reduces the cation mixing space, the price is cheaper than lithium cobalt oxide, and the high energy density is the biggest advantage of the ternary lithium ion battery. Determine the basic efficiency and cost of the battery, stabilize the layered structure of the material, cycle attenuation, and even the battery of the same ampere hour. The battery capacity of the same model is slightly lower than that of the lithium cobalt oxide battery, and the voltage resistance is slightly higher, resulting in electrochemical performance. Deterioration, the capacity is reduced, and the average voltage is slightly lower (the battery industry is called the battery platform). The biggest feature of ternary lithium-ion batteries is that the unit electric energy is relatively large. The greater the concentration of nickel ions in the lithium ion layer, the greater the specific capacity and the higher the conductivity. The voltage platform is an important indicator of battery energy density. The capacity and safety are more balanced. This is the result of comparing with the lithium iron phosphate battery. The gram capacity is slightly higher but the compaction ratio is lower. The ternary lithium ion battery is a kind of lithium ion battery: nickel cobalt manganese Lithium-ion batteries using lithium ions as cathode materials are commonly known as ternary materials lithium-ion batteries. However, due to the similar radius of lithium ions and nickel, which improves cycle and efficiency performance, the more difficult it is to deintercalate lithium ions in the layered structure.
